Conduction of a comparative proteomic mass-spectrometric (MS) analysis using a personal database of V. cholerae protein mass-spectra and genetic VNTR-typing of cholera causative agent strains. V. cholerae O1 El Tor strains - 7, V. cholerae non O1/non O139 - 2. Protein profiling and VNTR-genotyping of strains was carried out on MALDI TOF-MS Autoflex (Bruker Daltonics) mass-spectrometer and SIS Cholera-strains-VNTR. The established community of a proteomic profile of epidemic cholera vibrio strains isolated in 2010 - 2012 in Moscow allowed to determine Indian origin of a toxigenic strain isolated in Taganrog in 2011. M/z proteins distinguishing V. cholerae O1 and non O1/non O139 strains were identified. Proteomic analysis confirms the results of VNTR-genotyping. Study and typing of V. cholerae members with determination of their origin and phylogenetic relationship is possible using a collection of V. cholerae mass-spectra.
